PAR tempfile issue

jettero has asked for the wisdom of the Perl Monks concerning the following question:

I actually asked this question on the par-perl mailing list. But that list doesn't get a lot of traffic. If any PAR fans know how to deal with this:

$ pp -r example.pl 

Error in tempfile() using /tmp/par_priv.9899.tmp/XXXXXXXXXX.so: Parent
+ directory (/tmp/par_priv.9899.tmp/) is not a directory at ../blib/li
+b/PAR/Heavy.pm line 79
Compilation failed in require at script/example.pl line 4.
BEGIN failed--compilation aborted at script/example.pl line 4.

I'd feel most enlightened by your comments...

I'm not a PAR user, but I'll throw out a couple of wild guesses (I'm assuming from the .so and /tmp that you're running some Un*x flavour or other...): /tmp isn't there/isn't writeable? Maybe the /tmp directory isn't named /tmp, on your system, or the permissions are odd... /tmp is full? Maybe you're out of /tmp space, or have exceeded some quota. (Before someone points out that "out of /tmp is also out of swap", that's not necessarily true on all systems.) What happens if you mkdir /tmp/xxx? Does the directory get created properly? I hope this helps... -- Mike	[reply]

Nope... it's not a perms or directory issue or anything. It's something I'm doing wrong with the pp app. Try it yourself, it's kinda neat. `perl -MCPAN -e 'install PAR'` should be trivial. `pp -r -e 'print "hello world!\n"'` should make an executable that's like a meg big ... but it prints hello world and you don't need to have perl installed to run it. The problem comes in when I try to make an executable from an app that uses Curses::UI. I don't know why that's special, but it doesn't seem to work -- resulting in the tempfile issue above. I also compiled an app that uses a few modules like Crypt::Rot13 that DID work just fine.	[reply] [d/l] [select]

Line 79 of `Heavy.pm` is attempting to create a temporary file using `tempfile()` in File::Temp. If memory serves, `tempfile()` will not create a directory if it doesn't already exist (that's what `tempdir()` is for). So `File::Temp` appears to be complaining here: `unless (-d $parent) { ${$options{ErrStr}} = "Parent directory ($parent) is not a directo +ry"; return (); }` [download] Line 79 of `Heavy.pm`: `if ($ENV{PAR_CLEARTEMP}) { ($fh, $filename) = File::Temp::tempfile( DIR => ($ENV{PAR_TEMP} \|\| File::Spec->tmpdir), SUFFIX => ".$dlext", UNLINK => ($^O ne 'MSWin32'), ); }` [download] Hmm, looks like `Heavy.pm` is telling `File::Temp` to create a file in the `$ENV{PAR_TEMP}` directory which is where your problem lies as `$ENV{PAR_TEMP}` obviously doesn't exist. Can't really help you out any more than that as I know little/nothing about `PAR` and why/how `$ENV{PAR_TEMP}` is created/used etc... -- vek --	[reply] [d/l] [select]

case anyone finds this thread later... the solution was an upgrade to 0.71 -- which wasn't released at the time of the posts above.	[reply]
